SBAU395 april 2023 DAC39RF10
The DAC39RF10EVM is an evaluation board used to evaluate the DAC39RF10, digital-to-analog converters (DAC) from Texas Instruments.The DAC39RF10 is a family of single and dual channel digital-to-analog converter (DAC) with 16-bit resolution. The devices can be used as single channel or dual channel non-interpolation DACs. The device can also be used as interpolating DACs in either direct RF sampling mode or baseband mode. The maximum input data rate is 20.48 GSPS in single channel mode or 10.24 Gsps in dual channel mode or baseband mode. The device can generate signals of up to 10, 7.5, and 5 GHz signal bandwidth (8, 12, and 16-bit input resolution) at carrier frequencies exceeding 8 GHz enabling direct sampling through C-band and into X-band This evaluation board also includes the following important features:
with an option to bypass the transformer and use the outputs differentially.
To improve signal routing quality, serial lane polarity is inverted with respect to the standard FMC VITA-57 signal mapping. Signal mapping and polarity is shown in Table 7-1).
DAC39RF10EVM can use used with the TSW14J59EVM board(pattern generator board). TSW14J59EVM can quickly and easily interface with the DAC39RF10EVM.
For now only 64b/66b encoding modes from serdes data rate from 6Gbps to 12.8Gbps are supported by the TSW14J59EVM. The support for 8b/10b modes and lower serdes rate will be added to future release of HSDCpro software.
The High-Speed Data Converter Pro (HSDC Pro) software is used to communicate with the TSW14J59EVM and is used to generates the data pattern for DAC39RF10.
The TSW14J59EVM takes the generated data pattern, encodes the data, stores the data in memory, and then sends to DAC39RF10EVM through the the high-speed serial data link(JESD interface).
With proper hardware selection in the HSDC Pro software, the TSW14J59 board is automatically configured to support a wide range of operating speeds of the DAC39RF10EVM, but the TSW14J59EVM board may not cover the full operating range of the DAC device.
